Answer:
-17.25
Step-by-step explanation:
So first you add -8.3 and -7.7, from there you get -16.
-1 1/4 would be -1.25 as a decimal. So all you do is add -16 and -1.25 and you get -17.25 as your answer
Answer:
v = (base x height x length)/2
(7 x 10 x 13)/2 = 455 x 3.15 = 1433.25$

The surface
![S](https://tex.z-dn.net/?f=S)
can be parameterized in cylindrical coordinates using
![\mathbf r(u,v)=(x(u,v),y(u,v),z(u,v))=(u\cos v,u\sin v,u)](https://tex.z-dn.net/?f=%5Cmathbf%20r%28u%2Cv%29%3D%28x%28u%2Cv%29%2Cy%28u%2Cv%29%2Cz%28u%2Cv%29%29%3D%28u%5Ccos%20v%2Cu%5Csin%20v%2Cu%29)
where
![4\le u\le5](https://tex.z-dn.net/?f=4%5Cle%20u%5Cle5)
and
![0\le v\le2\pi](https://tex.z-dn.net/?f=0%5Cle%20v%5Cle2%5Cpi)
. The surface integral is then equivalent to
![\displaystyle\iint_Sx^2z^2\,\mathrm dS=\int_{v=0}^{v=2\pi}\int_{u=4}^{u=5}(u\cos v)^2u^2\left\|\mathbf r_u\times\mathbf r_v\right\|\,\mathrm du\,\mathrm dv](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Ciint_Sx%5E2z%5E2%5C%2C%5Cmathrm%20dS%3D%5Cint_%7Bv%3D0%7D%5E%7Bv%3D2%5Cpi%7D%5Cint_%7Bu%3D4%7D%5E%7Bu%3D5%7D%28u%5Ccos%20v%29%5E2u%5E2%5Cleft%5C%7C%5Cmathbf%20r_u%5Ctimes%5Cmathbf%20r_v%5Cright%5C%7C%5C%2C%5Cmathrm%20du%5C%2C%5Cmathrm%20dv)

Answer:
-240°, -600°
Step-by-step explanation:
Coterminal angles are angles that land in the same spot around a circle.
So, that means they do full turns of the circle to reach each other.
To find coterminal angles of a given angle (here 120 degrees), you add or subtract 360 (the number of degrees in a full circle). That can go in both positive or negative directions.
So, from 120 degrees, let's find the coterminal angle that is 1 rotation above and one rotation below:
120 + 360 = 480
120 - 360 = -240
You see that 480 isn't among the possible answers, so one part of the answer is -240. If you subtract another 360 degrees, you end up with -600 degrees... so the answer is -240°, -600°
